heal.abstract We have used the Cornwall--Jackiw--Tomboulis method of composite operatorsand its formulation at finite temperature by Amelino-Camelia and Pi, in orderto calculate the effective potential of the O(4) linear sigma model beyond theHartree approximation. We have obtained a system of gap equations for theeffective mass of sigma and the pions as well as for the condensate, the en
